To all whom it. may concern:

Be it known that l, loan H. Session, a citizen of the United States,residing at Decatur, in thc county of Benton, Stuto of Arkansas, haveinvented certain new and useful lmpiovcrncnts in Rotary Engines; and ido hereby declare the following to he a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the some.

,This invention relates to rotary engines and more particularly to thatclass including a two-part casing in which is mounted a wheel carrying aplurality of piston hoods against which, stcum, from it supply pipeimpinges and the primary object of the invention is to provide animproved structure oi this class which will no easy running and whichwill comprise but few parts which muy be readily disassembled forcleaning or for repair Furthermore the invention resides in theprovision of a wheel or disk having piston heads of novel construction.

.ln the accompanying druwin s -Figurc l is a side elevation of a rotaryengine constructed in accordance with my invention. Fig. 2 is a planview thereof. Fig. 3 is. a detail vertical transverse sectional viewthrough the same. Fig. 4 is :1 detail perspective view of a portion ofthe disk carrying the piston heads, several of the piston heads beingalso shown in perspective, and Fig. =3 is a view similar to Fig. 3showing slightly modificd form of my invention.

Referring more specifically to the drawings there is shown a hose frameincluding spaced sills 5 and 6, the sills 5 being designed to supportthe engine proper and the sills 6 being provided with hearing box 7 forhe engine shaft. p I

The engine proper comprisw u casing formed of it pair of soc-Lions 8which ore identical in construction and which are each in thc form of n.Zllf l halving formed therein an annular sen]i-cylindrical channel 9which is located adjacent the outer edge of the disk, the said channelforming. when the sen-ions ztL'f ('UIlIlHCttHl. a continuous cylinder.That portion of cnch disk which lips outwardly,oflthc chaiiucl formedtherein sr-rvcs as ailungc 10 by" mean:- of which s ,-t ions may besecured together there being a plurality of bolts 11 engaged through thsaid flnngc for tho purpose stated. I

The Web portions of the m mbers, or in other words that portion of catchmember whi h lics inwardly of the channel, are in spuccd rclation withrespect to each otlicr and re civcd lictwr-cn the we}; porti ns is adisk 12 which carries upon its pcriphcry u plurality of piston h ods 13which are formed integral withthe disks and which are concavo convex inform, it being understood that the saidpiston h ods movo in thecontinuous cylinder formed by the channels .0 in thc cylinderincinhc'rs. To brace the connection of the piston heads with the disk12, thc said heads are gradually thickened as they approach thcperiphery of the disk as indicated by the numeral 13" and the lower edgeof the rczir face of ouch piston head terminutes at the lower edge ofthe forward fucc oi the next adjacent piston head in rear of the onemcntioncd.

The numeral 14 denotes the engine shaft which is engaged through anopening formed centrally through the disk 12, the said disk beingfixcdly st urcd to the shaft and being secured to the flare ill thispoint as at 15. I

An opening 16 is formed through the disks 8 at the point correspondingto the opening in o disk and the wheels of.the opening 16 are tapered torccciw: the flared portion of the said disk '12, and hcncc'thtedges oithe opening in the disks 8 through which the shaft 14 is engaged, do notcontact with the shalt.

- In order that the engine may be mounted fixedly upon its supportingfru1ne, pairs of attaching brackets l7 are formed upon opposite sides oithe cylinder of the engine at corresponding points in a'plunc slightlybeneath that occupied by the engine shaft 14 and the engine is securedby means of the said brackets and bolts are engaged therethrough uponthe ls 5.

A steam inlet pipe 18 communicates With the con tinuous cylinder, formedby the annular channels 9, adjacent the top of the cnginc casing andslightly to one side of the connecting flange for the scctions thcrcoi,and a sic-1m outlet pips.- lcads from u conr'csprmding point ittljtlljllh the lower end of the asing. 7

In the form of my invention shown in Fig. 5 the Sections comprising thccasing of the engine iustcud of being pmvidcd with scnii-cylindricnlchannels are providcril with annular groo't'cs of such construction thatwhen the sr'cti nsare connected continuous rectangular pussugc wuyformed and scrx'cs as the cylinder of the engine und in this form hollowpyramidal piston heads 20 arc cmploy d.

What claimed is'- An r-ngiu of the claw dcscrihwl haviur a cdntinuouscyliud r, :1 disk in llncylinder. and coucuvo-couvex comprising atcasing mounted for rotation piston hoods carried by the disk, sold headshaving tln-ir couvcxr-d faces ex tended to the concave for: of the next,adjacent rearward hlndc and being thickr-ncd :iL thcirhose or point ofconnection with thc disk.

In t stimony win-roof. l uflix my signature, in presence "f twowitnesses.
